a Molecular structures of a switching unit DAE and fluorophore Cy3. b Photoswitching experiments performed on living zebrafish with dendritic nanoclusters internalized by permeation upon alternate irradiation with UV (365 nm) and visible (590 nm) light. Red circles represent the Cy3 moieties as covalently attached to the surface of dendrimers. (Reprinted with permission from Kim et al.58. Copyright 2012 John Wiley and Sons)
